The HP Mini 2140 shares the same basic silhouette as the earlier Mini 1000 and Mini-Note 2133 systems from HP. Because it has an aluminum case, like the 2133, it's a half-pound heavier than the plastic Mini 1000; it's a trade-off that may be worth it, however, as the metallic Mini 2140 feels as if it'll stand up to the rigors of the road better than a plastic Netbook.
